The seats were clean; the cabin looked very nice. The plane got me from point A to B safely. smoothest Lansing ever!

Flight was delayed 2.5 hours. No communication from the cockpit, 2 out of the 4 flight attendants we really crabby. Undersea storage was unusually small. I’m 5’8” and my knees were pressed against the seat in front of me and the seats are hard. My legs were numb for part of the trip.

Flight was fine

It was my first time on Frontier. I did not realize they charged for bags and they charged me $60 at the gate for my carry on. Very annoying. Will avoid in ththe future.

It was not noted that there would be an additional charge for carry-on luggage. My husband and I had to pay an additional charge of $90.00 for our luggage, that we were not anticipating. This was a HUGE let down!

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
